Cherry Blossom Predictions

Looks like predictions for when the cherry blossoms arrive are now posted. There's a map as well as more detailed lists, like the one for the Kanto (Tokyo) area. We are apparently scheduled for about March 24 in Yokohama and March 25 in Tokyo. For Tokyo, that will be three days earlier than "average" and 6 days earlier than last year, when they were late. Sendai will be announced (the prediction will be made, that is) mid-March, and Sapporo in early April.

I'd love to know how they calculate that average; I seem to recall reading that it was some like the average from 1975 to 2000? Have to dig the data back up...
